Breathing mattress for bed and method of making the same

ABSTRACT

A breathing mattress for bed includes a mattress body, which is prepared from a foam material and has a plurality of mounting holes, and a plurality of hollow elastic filler elements respectively mounted in the mounting holes of the mattress body for ventilation.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a mattress for bed and more particularly, to a breathing mattress. The invention relates also to the method of making the breathing mattress.

2. Description of the Related Art

Latex and foam materials have been intensively used for making mattress for bed. A latex or foam material mattress gives a comfort support to the user when the user is lying on the mattress. However, when the user is lying on a latex or foam material mattress for a certain length of time, the temperature and humility in the contact area between the user's body and the mattress will become high, causing the user to feel uncomfortable. In order to eliminate this problem, breathing structure may be added to the mattress. However, conventional mattresses having a breathing structure are commonly expensive.

SUMMARY OF THE INVENTION

It is one objective of the present invention to provide a breathing mattress for bed, which provides good ventilation.

It is another objective of the present invention to provide a breathing mattress, which is easy and inexpensive to manufacture.

To achieve these objectives of the present invention, the breathing mattress comprises a mattress body, which has a plurality of mounting holes, and a plurality of hollow elastic filler elements that are respectively mounted in the mounting holes for ventilation.

The present invention also provides a method of making a mattress comprising the steps of a) preparing a mold having a cavity and a plurality of upright pins in said cavity; b) preparing, equal to the number of said upright pins, a plurality of hollow elastic filler elements, and then sleeving said filler elements onto said upright pins respectively; c) filling up said cavity of said mold with a fluid foam material; and d) shape-forming and hardening said foam material so as to obtain the mattress.

The present invention provides still another method of making a mattress comprising the steps of a) preparing a plurality of hollow elastic filler elements and a mattress body of foam material; b) making a plurality of mounting holes in said mattress body; and c) fastening said filler elements to said mounting holes.

DETAILED DESCRIPTION OF THE INVENTION

Referring to FIGS. 1 and 2, a breathing mattress 10 in accordance with the preferred embodiment of the present invention is shown comprised of a mattress body 11, and a plurality of filler elements 20. The mattress body 11 is made by latex or any of a variety of foam materials, having a top wall 12, a bottom wall 14, and a plurality of cylindrical mounting holes 16 extending from the top wall 12 toward the bottom wall 14. The number of the filler elements 20 is equal to the number of the cylindrical mounting holes 16. The cylindrical mounting holes 16 are formed in the mattress body 11 over the area on which the user's body may rest. The filler elements 20 are hollow cylindrical elastic plastic members, having an annular cross section in transverse direction and a corrugated cross section in longitudinal direction. The filler elements 20 are respectively axially press-fitted into the cylindrical mounting holes 16.

As shown in FIGS. 3-5, the fabrication method of making the aforesaid mattress 10 includes:

step 1: preparing a mold 50 having a cavity 52 and a plurality of upright pins 54 in the cavity 52 as shown in FIG. 3;

step 2: preparing, equal to the number of the upright pins 54, a plurality of cylindrical elastic plastic filler elements 20 that have an annular section in transverse direction and a corrugated section in longitudinal direction, and then sleeving the filler elements 20 onto the upright pins 54 respectively as shown in FIG. 4;

step 3: filling up the cavity 52 of the mold 50 with a fluid molding material (latex or foam material) 56 and keeping the filler elements 20 peripherally maintained in contact with the fluid molding material 56 as shown in FIG. 5; and

step 4: hardening the molding material 56 and then removing the finished product, i.e., the mattress 10 from the mold 50 after form-setting.

Referring to FIG. 1 again, when the user lies on the top wall 12 of the body 11, the elastic material property of the mattress body 11 gives a comfort support to the user's body, and at the same time, the user's body is kept in close contact with the top wall 12 of the mattress body 11 and the top side of each filler element 20, allowing warn and wet air to pass downwardly away from the user's body into the gaps in the inside of the filler elements 20.

As indicated above, the present invention provides a breathing mattress for bet, which gives a comfort support to the user and, which is easy and inexpensive to manufacture.

Alternatively, the breathing mattress can be made by: preparing a mattress body from latex or foam material and a number of hollow filler elements, and then making a plurality of mounting holes in the top wall of the mattress body through a mechanical processing process, and then fastening the hollow filler elements to the mounting holes in the top wall of the mattress body. 

1. A breathing mattress comprising: a mattress body having at least one mounting hole; and at least one hollow elastic filler element mounted in said mounting holes for ventilation.
 2. The breathing mattress as claimed in claim 1, wherein said mattress body has a top wall and a bottom wall and said mounting hole extends from said top wall toward said bottom wall.
 3. The breathing mattress as claimed in claim 1, wherein said mattress body has a top wall and a bottom wall opposite to said top wall; said mounting hole extends through said top wall and said bottom wall.
 4. The breathing mattress as claimed in claim 1, wherein said mounting hole is formed in said mattress body over an area for supporting the user's body.
 5. A method of making a mattress comprising the steps of: a) preparing a mold having a cavity and a plurality of upright pins in said cavity; b) preparing, equal to the number of said upright pins, a plurality of hollow elastic filler elements, and then sleeving said filler elements onto said upright pins respectively; c) filling up said cavity of said mold with a fluid foam material; and d) shape-forming and hardening said foam material so as to obtain the mattress.
 6. A method of making a mattress comprising the steps of: a) preparing a plurality of hollow elastic filler elements and a mattress body of foam material; b) making a plurality of mounting holes in said mattress body; and c) fastening said filler elements to said mounting holes.
